PHILIP S. REYMAN, OF MOUNT CARMEL, ILLINOIS, ASSIGNOR TO JOHN C. KELCH,OF MOUNT CARMEL, ILLINOIS.

STAVE-JOINTING MECHANISM.

To all whom 'it may concern:

Be it known that I, PHILIP S. REYMAN, a citizen of the United States,and a resident of Mount Carmel, in the county of l/Vabash and State ofIllinois, have invented a new and Improved Stave-Jointing Mechanism, ofwhich the following is a full, clear, and exact description.

My invention relates to stave jointing mechanism, my more particularpurpose being to improve the means used for cutting the edges of stavesin order to give such edges the proper conformity to enable them to itagainst the adjoining edges of other staves, so that when the staves areassembled they will fit each other neatly and the barrel or otherreceptacle made from them will have, if desired, a suitable bilge.

More particularly stated, my stave jointing mechanism comprises aplurality of rotary saws mounted independently and adapted to swing inplanes crossing the general direction of rotation of the saws, andvariable form pieces to be used in connec- ,tion with these saws forguiding the latter in shaping the staves.

My invention further comprehends mechanism associated with the saws andform pieces above mentioned, for the purpose of swinging said saws insaid plane crossing the direction of rotation, and also means forenabling the operator to move at will, relatively to the saws, the formpieces and staves resting thereupon.

My invention comprehends also various mechanical features for improvingthe general eiciency of stave jointing machines and devices relating tothe same.

Reference is to be had to the accompanying drawings forming a part ofthis specication, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a central fragmentary plan view of the device, showing thesaws and two-part form pieces and mechanism immediately associated withsaid saws and form pieces; Fig. 2 is a vertical Asection takensubstantially on the line 2-2 of Fig. 1, looking in the direction of thearrow and showing the worm gearing used for swinging the saws in adirection lateral to the general plane of rotation of said saws; Fig. 3is a substantially centralvertical section upon the line 3 3 of Fig. 2,looking in the direction of Specication of Letters Patent.

the arrow, and showing how one of the saws acconnnodatcs itself to theconditions required in cutting a stave; and Fig. 4 is a fragmentarysection on the line 4-4 of Fig. 3, looking in the direction of thearrow, and showing how the form pieces are slidably mounted.

Mounted upon pedestals 5, 6 are bearings 7 8, and journaled within thesebearings is a horizontal shaft 9. Journaled upon a portion of this shaftis a bearing sleeve 10. A worm sector 11 is, by aid of a key 12,connected rigidly with the shaft 9. Another worm sector 13 is connectedby a key 14 with the bearing sleeve 10.

Two worms 15, 16 are geared together by aid of pinions 17, 18 and aredisposed partially within an oil basin 19 which is integral with thepedestal 5. Adjacent to the worms 15, 16 are bearings 20 through whichextend two parallel horizontal shafts 2l, 22, upon which the worms aremounted rigidly. A hand wheel 23 is used for turning the shaft 22 andthus communicates motion to the worms and sectors.

The worm sectors 11, 13 are provided respectively with portions 24, 25extending obliquely upward, and are further provided with bearings 26,27. Extending through these bearings and supported thereby arehorizontal shafts 28, 29. Above the bearing 26 the upwardly extendingportion, 24 is provided with a fork 30. Upon the opposite side of themachine is a similar fork 31 integral with the upper portion of thesector 13, Pulleys 32, 33 are supported by the forks 30, 31. For thispurpose I provide each of these pulleys with a shaft 34, as indicated inFig. 2.

For the purpose of supporting these two shafts and the pulleys 32, 33, Iprovide bearings 35, 3G, 37, 38, the bearings being disposed at the topsof the forks 30, 31. Two revoluble saws 39, 40 are supported by theforks 30, 31, and disposed intermediate these saws at the lower portionsthereof are two form pieces 41, 42, of the shape indicated. Each ofthese form pieces at its upper surface has a general arcuate form, theform pieces thus being higher in the middle than at the ends thereof.Each form piece is also thicker at its middle than at its ends, as willbe understood from Fig. 1.

The two form pieces 41, 42 are provided at their ends with lugs 43, 44and with stop plates 45, 46 for a purpose hereinafter described. The`form pieces 41, 42 are also provided with bearings 47, 48, 49, 50whereby they are sustained. These bearings encircle the horizontal rods28, 29. Mounted upon these bearings are guides 51, 52, 53, 54 arrangedin pairs as indicated in Figs. 1 and 4. rhese guides enable the formpieces 41, 42 to swing toward or from each other, carrying with them therods 28, 29 and yet holding the various parts in proper workingrelation. Mounted upon each fork 30, 31 are brackets 55, 56, andjournaled upon these brackets are levers 57, 58 carrying presser wheels59, 60 and weights (51, 62.

At 63 (Fig. 3) is shown a stave which is being cut. The horizontal rod28 is supported at its ends by brackets 28a, 28h, se-

cured thereto by keys 28, 28d, the horizontal rod 29 being supportedsomewhat similarly by brackets 29a, 29h, the bracket 29a, however, beingfree to turn upon the shaft 9 while the bracket 29b is keyed at 29I2rigidly upon the bearing sleeve 10. The horizontal rods 28, 29 areadapted to approach and recede from each other, and in doing this thesaws 39, 40 are similarly moved toward and from each other; the anglebetween the general planes occupied by the saws being changed with thedegree of rotation in a plane crossing the general plane of rotation ofthe saws.

The operator, by turning the hand wheel 23 back and forth, causes theworms 15, 16 to turn, the rotation of one of these worms being alwayscontrary to the rotation of the other. rIhe worm sectors 11, 13 are thusturned in opposite directions in obedience to the control of the handwheel 23. As the worm sectors 11, 13 thus turn in opposite directions,the horizontal rods 28, 29 ap.- proach and recede from each other, thesaws 39, 40 being thus under control of the operator.

rEhe operation of my device is as follows: The operator, by turning thehand wheel 23, b-rings the form pieces 41, 42 into proper relation forcutting stave joints, I will say, for some particular purpose. rEhecarriage, including the form pieces 41, 42, is moved to the rightaccording to Fig. 3j The presser wheels 59, G0 are now raised slightlyby lifting the weights 61, 62 and a stave blank 63 is inserted in themachine. This is done by pushing one end of the stave blank down againstthe lugs 43, 44. The downward pressure of the weights 6l, 62 causes thepresser wheels 59, 60 to hold the stave blank firmly, but yieldingly, inposition. During all this time the saws have rotary motion. The staveblank having' been adjusted as described, the carriage is moved to theleft according to Fig. 3. rlhe saws engage the adjacent end of the staveblank and cut operated upon.

through it, the inclination of the saws relatively to each othercontrolling the inclination of the cut edges of the blank. As thecarriage travels to the left, the action of the presser wheels 59, 60.is such as to gradually rock the blank as indicated in Fig. 3. That isto say, as the carriage moves along, the presser wheels 59, 60 followinggenerally the contour of the upper surface of the form pieces, cause theblank 63 to'constantly shift its position, the end of the blank at theleft gradually rising and the opposite end being gradually lowered. Thepresser wheels being stationary in regard to the general position of thesaws necessarily engage the stave blank at points immediately adjacentto the saw teeth, that is, those particular teeth which at any instanthappen to be cutting. The pressure is preferably applied just a littlein frontof these teeth, as will be understood from Fig. 3. The blank,while constantly changing its position, is at each moment. pressed hardupon the form pieces, the pressure being exerted at the exact pointwhere it will do the most good in holding the stave blank steady as thelatter is being There is thus little or no tendency of the rotating sawsto displace the stave blank, the operating pressure of the saw teethbeing so distributed relatively to the pressure exerted by the presserwheels 59, 60, that the operation of the saw tends to prevent, ratherthan to permit, the stave blank to be dislodged or otherwise disturbed.The pressure of the presser wheels 59, 60 has, it will be observed, aclose relation to the pressure exerted by the saw teethv uponk the staveblank in the act of cutting the same. The degree of curvature. given tothe form pieces 41, 42 must necessarily tend to control the shape of thebarrel or other member for which the stave is being prepared. Not onlycan the curvature of the bilge be controlled perfectly, but the diarne-`ter of the prospective barrel can also be controlled by aid of thisapparatus.

The parts are so arranged that the aXis common to the shaft 9 and thebearing sleeve 10, represents the geomet-ric axis of the prospectivebarrel or other member to be made up out ofthe staves thus prepared.Moreover, the form pieces together constitute a divided form whereby themachine is easily adjusted to various widths of staves.

Having thus described my invention, I claim as new and desire to secureby Letters Patent: f'
